Current evaluation

Feature request to have imagecraft generate sparse images (e.g. via img2simg) for Ubuntu Core, since field deployments only use/deliver sparse images. Untriaged: no labels, no comments, no activity in 158 days; feature confirmed absent from codebase.

Suggested action: needs triage

Reason: The issue has no labels, no assignee, and zero comments or maintainer response in 158 days, so it has never been assessed. The request is legitimate and verifiably unimplemented (no img2simg/simg support anywhere in imagecraft/pack or commit history), and the reporter — a maintainer — argues it blocks deliverable Ubuntu Core images, so it warrants triage rather than closure.

Issue body

### Check existing issues - [x] I've verified that this request isn't described by any existing issues. ### Request For Ubuntu Core image the imagecraft should be able to create sparse images. ### The problem it solves UbuntuCore is all about reducing the footprint of the image and going fast when updating using snap delta update. Having to flash the whole drive when you just want to update the image goes against that philosophy. "img2simg" can be use to achieve this. I would really add that in real world within field we only use/deliver sparse images so missing this feature will prevent any deliverable image to be created with imagecraft.
